Abstract

Acute lung injury after oesophagectomy is well recognized but the risk factors associated with its development are poorly defined. We analysed retrospectively the effect of a number of pre-, peri- and post-operative risk factors on the development of lung injury in 168 patients after elective oesophagectomy performed at a single centre. The acute respiratory distress syndrome (ARDS) developed in 14.5% of patients and acute lung injury in 23.8%. Mortality in patients developing ARDS was 50% compared with 3.5% in the remainder. Features associated with the development of ARDS included a low pre-operative body mass index, a history of cigarette smoking, the experience of the surgeon, the duration of both the operation and of one-lung ventilation, and the occurrence of a post-operative anastomotic leak. Peri-operative cardiorespiratory instability (measured by peri-operative hypoxaemia, hypotension, fluid and blood requirements and the need for inotropic support) was also associated with ARDS. Acute lung injury after elective oesophagectomy is associated with intraoperative cardiorespiratory instability.
